I have a Logitech C920 and am looking to upgrade. Something suitable for streaming.

Some annoyances with the Logitech: sometimes autofocus fails and poor reproduction of blacks. Ex: Lack of detail when a black cat is on screen.

I already have a nice mic-- the webcam doesn’t need one.

    i’ve had a lot of luck with the logitech brio which is a 4K WebCam, the only issue that I’ve run into is the fact that you have to make sure that it is plugged in to a USB 3.0 and not 3.1 port.

    I recently purchased the Anker PowerConf C200 2K webcam and it has been great on Linux. Crisp image and no issues with focusing. It’s currently on sale at Amazon

      I recently found out about Anker and I bought a wired ergonomic vertical mouse as I had been experiencing wrist pain recently. High quality for a very low price point, and from the looks of it most of their products are like that. Also helped with the wrist pain!

    You’ll have to forgive me, as I haven’t tested this personally on Linux yet, but this webcam is a USB 3 device and doesn’t have any special drivers. It should work plug-n-play.

    The reason I bring it to your attention is that it has a nice physical lens for focusing, aperture, and zoom; all separate. It’s 4k 30 fps and I can confirm that the picture is really nice.

    Wow, I’ve used a C920 and now a C930 and never had any issue, although I just do meetings.

    I’m interested on seeing opinions too.

      C920 is good enough for meetings. I solved the focus problem using the traditional Linux method of writing of udev rule which launches a timer when it’s plugged in, which periodically launches a systemd service, which runs a bash script to make sure it self-corrects at least every 5 minutes.

      ❯ cat /etc/udev/rules.d/90-video4linux-webcam-config.rules
KERNEL=="video[0-9]*", SUBSYSTEM=="video4linux", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="0892", TAG+="systemd", RUN{program}="/bin/systemctl start video4linux-webcam-config@$env{MINOR}.timer" ENV{SYSTEMD_WANTS}="video4linux-webcam-config@$env{MINOR}.timer"

      ❯ cat /etc/systemd/system/video4linux-webcam-config@.timer

  exit 1
fi

        I’m using a C920 on Debian and I don’t have focus issues. I remember that once it was permanently stuck out of focus but unplugging and plugging again fixed the issue. Never had any other issues in years.

      My c920 now glitches out and refuses to stream video after about 10 minutes of use (mic still works tho). After some unknown long period of time, it resets and works for another 10 minutes
